SAFETY-RAZOR#SHAREENNG DEVICE.

To all ywhom it may concern.'

Be it known that I, SIMON KLEIN, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful lmprovements in Safety- RaZOr-Sharpening Devices, of which the following is a description in mich full, clear, and exact terms as will enable any person skilled in the art to which it pertains to make and use the same.

My invention relates to that class of safety razor sharpening devices in which the passage of the strop between the rollers in the trame operates to rock the razor holder back and forth so that the razor will be properly sharpened.

. My invention resides in certain novel features of construction in said safety razor sharpening devices all of which 'will be fully pointed'but and described hereinafter.

Reference is now had to the accompany-v ing drawing which represents as an example the preferred embodiment otl my invention andl rn which draw1ng4 Figure `1 is a front elevation of the device embodying my improvements; Fig. 2 is a sideelevation of the same; Fig. 3 is a crosssection on the line 3-3 of Fig. 1 and Fig. 4 is a perspective view of the combination holder, rock-bar and gearing.

Referring to Fig. 1, 10 indicates a handle which is screwed or otherwise connected to a trame 11. 12 is a. roller which revolves within the frame its ends projecting through theA `trame and having" pinions 13 attached thereto. Below the roller 12 a bar `14 is fitted in slots in the frame 11 and is adapted to be moved up andI down said slots. Upon the bar 14 are sleeves 15 which revolve Yaround the bar as' an axis. Aisprinv' 16 lies fiat upon the bottom of the frame 11 its ends beiner curved up to engage the bar 14: at openings between the sleeves 15 provided for the purpose. a f fainst the bar 14 and except when pressure is exerted upon the bar 14 in the opposite direct-ion it is held against the upper ends of the slots in which it slides. The pinions 13 engage the gears-17 which are pivoted on pins 1S around which however they can only revolve part way as their perimeters are not complete circumferences but are interrupted by the rock bar 19 which is formed ot' the same piece ot metal as'the gears 17. On the top of the rock bar are wings 20, also formed Speccation of Letters Patent.

of the same piece of metal as the gears 17 and rock bar 19, which are bent upward and Between Vthe wings 20 is. placed a sheet of metal 21 which lies llat against the interior surface of the wings and extends beyond their edges.

,When in operationthe razor blade is inserted between the ends of the lining sheet 21 as shown in Fig. 3, and as also shown in said ligure, the razor'strop is passed between the roller 12 and the sleeves 15 a tight engagement being secured'b'ecause the spring" 1G presses upward the. b ar 111- and this pressure is communicated to the sleeves 15. YWhen the strop is drawn to the right the revolution ofthe roller 12 is communicated to the pinions 13 w iich in turn actuate the gears 17 to which the rock bar 19 is attached and as the wings 20 are of a piece with the rock bar the razor is rocked to the right presenting' one side to the strop 'until the end of the strop is reached. The strop is then.

drawn to the left and the device acts inthe opposite direction. the razor being' rocked to the left and presentingits other side to the strop until the other end of the strop is reached when. same is again drawn to the right. It will be Vseen that by this means the razor is sharpened on each side to an equalV degree.

lt is well. for me to observe that devices for obtainingthese results are verv common and that my invention resides in cer- .tain special features ot' construction which are the introduction ot the spring 16 to hold the sleeves 15 in tight enaaggeinent with the razor strop and the formationof the gears 17. rock bar 19 and wings 2O from the same piece of metal as best shown in Fia". t.

The advantage oli the use ot' the'- spring 16will be apparent because without it the necessity arises ot' al ways obtaining a strop of a thickness equivalent. to the space between the sleeves 15 and the roller 12. The method of makina' the gears. rock bar and wings of the same piece of metal while involving` no advantage in operating the device is ot great importance to the manufacture becausethe part of the device can in this way be manufactured by two operations, c.. stamping` it out in correct form and then bending` up the wings.

Having thus described my invention, wha I claim as new and desire to secure by Letters Patent of the United States is 1. il. blade holder consisting 0l. a single piece of sheet metal having resilient blade y gripping Wings projecting therefrom in one 2. A blade holder consisting ofa singlepiece of sheet metal having opposed resilient blade gripping Wings projecting in one dii ,rection and integral portions projecting in the opposite direction and having segmental gears formed thereon, the last mentioned portions further having perforations con centric with the gears to receive a journal shaft.

In testimony whereof I have hereunto.

signed my name in the presence of two Witnesses.
